That (pulling a drive from an array) sounds like an expensive, risky (you have to open the box, after all) and time-consuming way to do backups. raid1 is a great way to prevent some disasters, but (as Rick pointed out) it's not for doing backups.
How much data are you needing to back up? More than 4GB at a time? If not, you could use dd piped through gzip (or bzip2) to make image backups that you write to a DVD. DVD burners are pretty cheap these days. Alternatively you could go with a backup service. There are plenty of them out there. There are also backup appliances, but then you're really talking about money. -CMP On 3/15/06, WA Brown <[EMAIL PROTECTED]> wrote: > Thats some of what I need to know.
